The mathematical essence of contextuality lies in the similarity of random variables answering the same question in different contexts: contextuality means they are less similar when considered within their respective contexts than when isolated from them. This book presents a principled way of measuring this similarity and distinguishing two forms of context-dependence: contextuality and disturbance. While applicable across a broad range of disciplines, the concept of contextuality in this book is closest to that in quantum physics, where its special forms \u2013in the absence of disturbance \u2013 are known as Bell nonlocality and Kochen\u2013Specker contextuality. This systematic introduction requires no prior familiarity with the subject and a very modest mathematical background.
